My apartment on the Lower East Side is actually a 2br, but I use one room as an office space. It's perfect for a single person or a couple. It's about 600 sq ft, and very quiet. The bedroom fits a queen size bed, and the office is actually bigger than the bedroom, but the pictures don't really convey that. It's really sunny with lots of windows and high ceilings and in good shape. The kitchen is open into the LR, and you can actually cook here. There is a dining table that opens up larger if needed.
*Many of my personal belongings have been removed from the office from when the pictures were taken, so you'll have more space for your things*.
